Date: March 31, 2007
Bugs: #171681
ID: 200703-27

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Synopsis
========
Squid is affected by a Denial of Service vulnerability.

Background
==========
Squid is a multi-protocol proxy server.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-proxy/squid < 2.6.12 >= 2.6.12

Description
===========
Squid incorrectly handles TRACE requests that contain a "Max-Forwards"
header field with value "0" in the clientProcessRequest() function.

Impact
======
A remote attacker can send specially crafted TRACE HTTP requests that
will terminate the child process. A quickly repeated attack will lead
to a Denial of Service.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Squid users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/squid-2.6.12"

References
==========
[ 1 ] CVE-2007-1560
